To all 'whom t may concern:

Be it known that I, JAMES C. Cnrroxmrr, a citizen of the United States,residi at El Paso, in the county of El Paso and rlate of Texas, haveinvented certain new and useful Improvements in Hydrocarbonlurners; andI do hereby declare the followmg to be a full, clear, and exactdescription of the invention, such as will enableothers skilled in theart to which itappertains to make and use the same.

My present invention relates to improvements in hydrocarbon burners ofthat general type in which finely divided fuel, whether liquid, gaseous,or solid, or one comprising a mixture of two or more of these kinds offuel, is intimately mixed with air and ignited, and in whichthecombustin is made complete.

According to my present invention I provide an apparatus which Yisespecially adapted to burn a mixture of crude oil and gas, or crude oiland a lighter oil intimately mixed with t from thismixture finelydivided particles of solid fuel. such as coal dust, charcoal dust, orthe like; and then to add the sprays of liquid fuel or jets ofcombustible so that a high heat may be quickly attained and constantlymaintained. and whereby this heat may be conveniently controlled orregulated, or cut off altogether.

My invention will be more fully understood after reference to theaeconipanying drawings. in which similar 4parts are indicated b vsimilar reference s vmbols throughout the several views. and in whichFigure l is a sectional diagrammatic view. showing the completeapparatus exclusive of the furnace.

Fig, 2 shows a section along the line 2- of Fig. 1 and looking in thedirection of the arrows.

Fig. 3 shows a section along the line 3-3 of Fig. 1. and looking inthedircction of the arrows.

Fig.' 4 shows a section along the line 4-4 of Fig. 1,`and looking in thedirection of the arrows; and Q Fig. 5 shows a section along the line ofFig. 1, andy looking in the direction of the arrows.

A represents a hollow shell provided with a rear chamber Al for the airto be supplied to the e aratus, and a front or mixing l; which chambersare separated rearward through the nozzles L.

air;` and to. inject into the Hame Y from each other by the diaphragm AJheld between the flanges a by means of the bolts a.

The chamber A is tapered toward its forward end, as at A, and terminatesin the contracted open end A1 which is preferably hexagonal 1n shape,for reasons'vhereinafter to vbe described.

The mixing'chamber is provided with a drain pipe A5 to carry o' anyliquid fuel, condensed steam, or other similar waste product.

Mounted in this main mixing chamber A are the series of air pipes B,which rojct the diaphragm into the air chamber A', and these pipes arebent forwardly, as at and b and terminate in By having the forward endof the main mixing chamber A of hexagonal form, the forward ends of thepipes B may be more compactly mounted therein, leaving small passagesbetween said pipes, andthus serving to causeithemiigture of air and.fuel passing in the space `betvieen said pi es .to follow narrowerpassages. and hence liecomc more intimately mixed.

'The fuel is fed into the mixing chamber through the nozzle c" at theend of the pipe which is connected by` the branch pipes C andl C2 to thesources of fuel supply D and D', the openings in these pipes C and `2being controlled by the valves 0 and c.

The reservoirs D and D are shown diagrammatically; the reservoir .D maycontain either light oil or gas under pressure, and the reservoir Dpreferabl contains heai'ier oil. such as crude oil. he mixing chamber Amay be supported in any convenient way, as b v means of the band E carried by the support E', as shown in Figs. 1 and 3.

.Hot air is l'n'ought from the furnace, or other convenient source ofair supply. through the pipe F and escapes therefrom through the pipes Fand' F2, controlled, respectively. by the valves f'y and f2. The

pipe F2 opens directly into the air chamber the pipes B.

In order to secure a further supply f aiiinthe space just referred to, Iprovide one or more pipes G which may be ooni controlled hy the vulve(f2.

"the hollow ring trolled by valves y. Additionul siii' under pressuremay be supplied, if desired, by the pipe G controller by the vulve g3.

H represents a hopper provided with fuel, .such :is coal dust, chai-couldust. or the like, which is fed through the pipe H controlled by thevulve /i und is supplied in front ol' the nozzles b". ln front of thispipe H l provide one or more hollow sliding rings I, perforated as uti', and adjustubly clamped :is ut I hy ineens of the set screw z" on thebar J. Liquid or gaseous fuel is fed to this hollow )ei-forutcd ring lthrough the pipe K, the ilexible connection K' and the pipe K2 from thereservoir L shown diagramrnuticiilly in Fig. 1. The passage through thispipe K2 is controlled by means of thc valve k.

M. represents the\couibuslion rhuiuher, preferably in the forni of uhollow cylinder with refractory lining ni und u i `iid elise m', whichcombustion chamber nur)4 be. held in suitable supports N, which muy bemoved longitudinally on the bnr .l and se( :d the desired position b vmenos of the sel srrev il. This coiiiliustion cliiimher should be. unranged close inl 'front ol' the burner ring l und have its outer endprojecting into the mouth of the furnace or lie-.ding elniniber. notshown.

The beiA J muy be supported in any con-` venient way as by ineens of thesu iport li iit one end and the support J ut tie other. as shown in Fig.1.

The operation of the eoiuplete apparatus is :is follows:

A limited iiniount oi' uliK is supplied to the chamber A und tothechumber (l 'troni either or hoth of the pipes l" or ('i". und ulimited amount of fuel, firefox-ably light oil or gus, is suppliedthrough the nozzle rf` and the :iir und fue] mixed :ire blown throughthe spaces between the pipes ll. und also nir escapes through thenozzles o", und the burner muy be lighted in froid of these nozzles o".Once lighted. .the suppliy oi' nir und fuel muy be increased until llie,hA- vire is running ut full blast, the supply of lighter oil Vor gusfrom the reservoir l) being controlled hy the` vulve c. und the supphlof crude oil from the reservoir 1) being These two will be intimatelymixed iii the. uiuin mixing chamber with the :iii- `coming in throng-lithe nozzle y" und the pipes (if. und the inixed iiir and fuel will pussthe nozzles o which will :idd still further :iir in finely dividedforni, and the mixture will burn fiercely.

into this' burning mixture pulverized solid fuel isV dropped through thepipe. Il und the ignited muss blown 'forward through l', und the liquidfuel or gus from the reservoiriL will come liii'linelv divided streamsthrong the lieiifoiutions i'. forming a fiercelyburning-mixture, und thucombustion ivill be coinpetd,in the combustion chamber M whence thehighly heated products of combustionwill be delivered to the furnace orheating chamber not shown.

I claim no invention in' an K articular form of furnace or heating ca r,since thc apparatus may be used with a great variety of types.

The position of the rin I the nozzles 'and the pipegl-I jus-ted bymoving the said rin backward or forward on the bar J, and similarly theposition of the combustion chamber M may Je varied by moving the samebackward or forward on said bar .L

While I have shown one ring' I, it will be obvious that a plurality ofrings iii'ay be used if desired. f

If it be desired to secure eater' cross sectional area-for the escape othe mixture ol' air and fuel from .the mixi chamber A2, it will beobvious that come o the pipes B muy be eut away, iis at b', leaving the.nozzles I, projecting forward, and the rear portion of said pipesremoved in which case the perforntions in the diaphragm A for themissing pipes should be closed or not provided ut I(ill.

ln order to clean out the apparatus the reur chamber A may be removedfrom the mixing chamber b v taking out the bolts a' und removing thediaphragm A and the ports carried thereby.

lt will be noted that the pipe Grl may be rlo'sed und hot nir alone maybe usedfrom the pipe l", or the valve g3 may be Wholly or partly openediermitting air to come in through the pipe il and. mingle with the hotair troni the pipe F. The pipe F may pass through or around the furnace,or hot air nur v be supplied from ,any convenient source not shown.

lt will be obvious that various modificar tions might be nuide in theherein described apparatus`-` sind in the construction, combination undarrangement could he used witliout'departing fioluthespirit oi' iiiyinvention, and I do not intend to limit the invention to such detailsexcept :is particularly pointed out vin the claims. i Having tLusdescribed my invention what I eluim and desire. to secure byLetters'Piitent ofn the United States is 1.
